MCs 2 Part and Jacks 3-2-1 Question

So currently Im using MCs new 2 part which is exactly the same as Jacks 3-2-1 except it has silica and some extra aminos I believe.

Theyre both virtually identical but Jacks recommends ~3g-A ~ 2g-B and ~1g Epsom throughout the whole cycle.

While MC recommends this 1594051859122.png.

2 completely different ratios but they both have the same ratios in their ingredients 5-12-26 with calcium nitrate.

Why does 1 include epsom salt and one doesnt even though their Magnesium ratios on the 5-12-26 are the exact same.

Ive been getting deficiencies here and there following MCs ratios that I fix with a foliar spray. I was wondering what if I just follow Jacks ratios with MCs 2 part?

Anybody else having some problems with MCs 2 part? I think im going to go back to the 1 part but I still got quite a bit of the 2 part to finish up. Whos ratio is correct?

Magnesium is usually kept at a low level in nutrients because they count on the fact that the water you're using is already infused with both Ca and Mg.

Perhaps they forgot to mention you might need to add more Mg in certain situations (low PPM water, RO etc), or they simply didn't want to mention that other things may be needed in conjunction with their product. Or perhaps they just expected the grower to know.

I know my water is < 65 PPM, and the amount of Mg in my Jack's 5-12-26 is not enough. I have to supplement by bumping it up by 20 PPM or so to keep my plants happy.

Jack full strength is 3.6 2.4 1.2 that's what they recommend

ya so why is MC recommending completely different ratios when they both are virtually identical nutrients? which ones correct and which one isnt?

Well it's a 2 part vs 3 part MC part A probably has more magnesium sulfate in it already with Jack you can just follow the label I would hope it's the same case with MC

its virtually identical. ive been thinking about it the last few days but thought Id come ask the nutrient experts on here why the completely different ratios they recommend.

Wow. They literally did just pretty much slap their own label on a bag of Jack's and called it their own.

Ya they added silica in theirs thats why I chose them over Jacks 3 part. But im going back to the 1 part of MC after this 2 part runs out. the 2 part is giving me problems in veg. Idk what the problem is exactly but Im thinking its the completely different ratio recommendations for the same exact nutrient. Im probably locking out nutrients following MCs ratios

Maybe megacrop needs some extra epsom. The part A and B combined is the same grams total for both just slightly different ratios if you ran either one with either recipe it would probably work. MC might have more part A because they don't recommend the epsom

Ya thats what I was thinking too. Ends up being a 3 part with epsom just like Jacks except they dont even mention it...thats messed up.

Took me a while to figure out what was going on with my plants when I started using this 2 part.

I thought the big draw to 3-2-1 is it's a start to finish feed schedule.
Thats how I run 4-18-38. seedlings to plants about to harvest get the same feed.

lol I know quite a bit of people IRL who are still on that train of thought. I told them about all these 1 parts (dynagro and maxibloom) and Jacks 3-2-1 and dry salts instead of paying for these Botanicare and Heavy16 and AN full 15 bottle diluted nutrient lines but they swear by their 15 parter.

My Uncle just pulled records in his grow after using Dynagro Foliage from w1 flower to harvest. He kept complaining about his leaves yellowing and sometimes even dying. He was using AN's full lineup b52... sensizym and all that jazz. He didnt want to deal with salts so I recommended Dynagro Foliage. not a single tree died or even yellowed til the last it was the last week.

What can ya do. Thats why I try to stay open minded about everything. I was that guy using AN's full lineup a year and a half ago.

oh wow really? i might give it a shot then. you prefer it over Jacks and MC?

Haven't tried Jacks. I was just about to switch to Jacks but after a little more thought I stayed with MB. They are pretty similar and again, my plants have never been better then the schedule I run now.

Not a fan of MC. If a company is constantly changing their formulas and the way they do business, I stay away. They used to be a good company (greenleaf) with some great additives with an honest business model. Not sure what happened.

I use this for veg with success, in coco.
Also note Im using a slighly different calnit.
17-0-0. Use 2.2 if 15-0-0 calnit.

Shame. Such a miniscule amount of Silica in MC 1 or 2 part. Requires 4+ grams per gallon to obtain one (1) PPM of silica in solition. So break out the Armor Si.

The aminos are a nice touch I guess.

Clowning with Jacks 321

How much ppm of base nutrients you add for cloning. I just pick me up some nutrients, an rapid rooter plug, and rootech gel. 350-ish
